JOYCE, or ennnnsiaoao, noa'rn CABGLINA, Assrenon r J'OIYCE-VEYNNING MANUFACTURING 00., INQ, or ennnnsnono; non-r}: CAROLINA, A CORPORATION or DELAWARE MANUFAGTURE'OF SUSPENDERS Application filed. November 8, 1930. Serial No. 494,378.

This application isa continuation-in-part of my application, SerialNo. 486,47 5, filed October 4, 1930, and the structure which'it disclosesrelates to the manufacture of sus- .penders and like articles, and proposes a novel method by which the slide parts and. the suspender web or strap, are co-operably laid together with the suspender web folded to. form the adjustable portion which receives the button, engaging loop, andfolded with the. slide parts in such arrangement that by the single application of pressure to the folded formation, the slideparts are assemble-d into an integral unit with the sus apender web insertedtherethrough and in operative adjustable relation to the slide.

The advantages of the new method are primarily a saving of time since by the old operation the suspender Web must be threaded :under and over and under the several transverse elements of a preformed slide by hand. Threading the web manually through the slide is sloW work and necessitates that considerable room be provided between the midjCllQ bar and the sides of the slide frame. This is the cause of excessive looseness of the adjustment of the web in the finished slide.

I By the present method the sides of the slide ;in a trough formed on the lower side of the middle bar, then allocating the middle bar with the suspender web therein retained, in position relative to the frame and the web folds, in the manner above described, and

;unitarily assembling the slide by pressure,

with the webin operative position as described.

Vith the above and other objects in view the process of the present invention is illustrated in the accompanying drawings in which:

Figure 1 is a View of the parts in assembled relation ready for pressing the slide parts together;

Figure 2 is a similar View in that form of the'invention in" which clamping the end of the web in the slide is not employed;

Figure 3 is a perspective view illustrating the elements of the sli'deand'a completed slide;

Figure 4 is a bottom plan View of the assembled slide and suspender web;

Figure 5 is a cross section taken along the line 5+5 of Figure 4; and v Figurefi is asection takenv along the line 66- of Figure 4.

vReferring now in detail to the several figures, and first adverting to that form of the invention disclosed in Figure 1, the reference character 1 represents a completed slide,'its

component parts being indicated at 2 and 3, 2 being referred to in the present specification as the frame and 5 as the middle bar.

Assembled slides such as those shown at 1 in Figure 3, ar e'old in the art vwith the exception so far as known of the dihedraltrou h, and arepu'rchased or made by suspender manufacturers as a separate and complete article of manufacture. The suspender web is 'ordinarilyassembled with respect to the complete slide by passinga free end of the web underthe side 4 of the frame over the middle bar 5,.under the side 6 of theframe, drawn through to 'a sufficient distance to form the fold whichretains the button holding'loop of the suspender and the free end then drawn back and inserted through the slide in such a" way as to be within the fold which holds said loop.

Asfhas been stated above, the threading of the web through the slide is quite time consuming, and 'thje'sides 4 and 6 must be spaced "quite some distance from the middle bar 5 inforderto facilitate the threading of the;

web'.

"The present invention employs the frame 2 an'dthe middle bar 5 unassembled, and

preferably, although 'notnecessarily employs the dihedral trough 7to finish and retain the free endof the web The sequence of the process steps can be readily understood from Figured. Where the end of the web is to be clamped within the slide the free end f the. web is first inserted into the dihedral troughof the middle bar 5, and the sides of the trough pressed olampably upon said web. The web is then folded back beneath the middle bar and folded upon itself as indicated at 9 to receive the button engaging loop 10. The upper fold of the web isbrought back and laid across the top of the middle bar. The frame is then laid down upon the top fold of the web in superposed relation to the middle bar. The opposite sides of a press are then brought to bear upon the interleaved portions of the web and slide thus assembled, and by application of pressure the frame is pressed firmly down upon the upper fold of the web and i the lugs 11 of the middle bar are turned over and pressed clampingly against the end portions 12 of the frame firmly uniting the middie bar and frame into an integral structure the same as is shown at 1 in Figure 3, the

-"web being thereby maintained in operative adjustable position in the slide with the'free end thereof caught in the trough of the middle bar 5. The clamped position of the parts is shown in Figures 4, 5 and 6 and does not differ materially from the position of the parts in a suspender and slide assembled by the old and more tedious method. Since no threading of the web through the slide has been necessitated, the width of the space indicated at 13 in Figure 5 between the sides of the frame and the middle bar of the slide may be made less than in the known construc tion so that the slidable portion of the web is more firmly held against displacement.

As will be noted at lt in Figures 5 and 6, the lower part of the press which afiiXes the middle bar to the free end of the web may be provided with die projections for indenting the under-fold of the middle bar thereby producing internal teeth which dig into the sus pender web and firmly hold the free end thereof against displacement.

Where the dihedral trough or its equivalent is not employed, the process is carried out by the web and the component parts of the slide being made ready for the press by first laying flat a length of web adjacent the free end. The middle bar is laid upon this and the free end folded over the middle bar. The portion first laid down is then folded over at a suitable point, to engage the suspender loop and then extended back so as to overlie the middle bar and the free end portion which lies above it. The frame is then placed upon the uppermost layer of the web in proper position relative to the middle bar and the press is then applied in the same manner as previously described.

While I have in the above description illustrated my novel method in connection with certain specific forms of slide and specific arrangements of the suspender web, it is to be understood that the breadth of the invention is not to be determined by the details of construction as shown, but by a fair and broad interpretation of the terms of the appended claims.

What I claim is:

1. Method of assembling a suspender web and slide in operative relation comprising, pinching the free end of a suspender web in a trough-shaped fold of a middle bar, arranging the frame and the middle bar of the slide in unassembled relation, and in inter-folded relation to the suspender web, with the free end of said Web secured to said middle bar as defined, the suspender web being folded so as to form the adjustable fold for a button engaging loop, and pressing together the )arts of both slide and web, inter-folded as de need, so as integrally to assemble the slide parts with a fold of the web slidably disposed between said frame and middle bar.

2. Method ofassembling a suspender web and slide in operative relation comprising, arranging the component parts of the slide, unassembled, in inter-folded relation to the suspender web, the latter being folded so as to form the adjustable fold for a button engaging loop, and pressing together the parts of both slide and web inter-folded as defined so as integrally to assemble the slide parts with a fold of the web slidably disposed therebetween.

In testimony whereof I afiix my signature.
